A video called "Flash Mob for Amy" is getting a bunch of hits online. The 'Amy' in it is a woman who got diagnosed with terminal cancer last year.

And the day before her 56th birthday, 50 of her friends showed up from five different states, and they surprised her with a flash mob dance to the Emotions song "Best of My Love". The video shows the dance, but also her reaction, which is great.

The song starts at :44, and the mob starts to show up at 1:07.
